<b>概要</b><br><blockquote>



Games and full screen applications using PureBasic functions run under a multitasking environment. 
This means that the user can switch back from full screen to the normal 
desktop. This change can be detected with this function and appropriate actions should be taken, 
such as <a href="../mouse/releasemouse.html">ReleaseMouse()</a>, pause the game, stop the sounds etc. This function must be called after <a href="flipbuffers.html">FlipBuffers()</a>, 
as the events are handled inside <a href="flipbuffers.html">FlipBuffers()</a>. 

 

</blockquote><p><b>参数</b></p><blockquote>
无.


</blockquote><p><b>返回值</b></p><blockquote>



Nonzero if the screen is still active, zero otherwise.
